WINDING-SPOOL SPINDLE AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent NO. 790,526, dated May 23,1905. Original application filed 1p1il29, 1904, Serial No., 205,527.Divided and this application filed August 16, 1904. Serial No. 220,891.

To all whom, t may concern:

Be it known that we, JACOB SALATHE and JOHN TAMBERLIN, citizens oftheUnited States, residing in Phoenixville, county of Chester, State ofPennsylvania, have invented certain new and useful Improvements inWinding- Spool Spindles and Bearings Therefor, of

vwhich the following is a specification.

Our invention relates to spinning-machines, and particularly to theimproved construction of spool-spindle and bearing therefor hereinafterfully described in connection with the accompanying drawing, and thenovel features of which are specifically pointed out in the claim.

The drawing is a vertical section of our improved winding-'spool spindleand bearing,

showing the same mounted upon the usual more fully described in ourpending application referred to. This pulley-sleeve6 loosely inclosesthe bolster-case 10 and is carried upon the step-bearing 11l within thelatter by means of the concentric tubular spindle 12, forming partthereof and extending into the bore of the bolster-case, in which it iscentered by a bottom collar 13, bearing upon a suitable step-bearingwasher or seat 14 and by an upper collar 15. A central tubular bolster16 within the bolster-case 10 rises loosely through the spindle 12 withits pulley-sleeve 6 and provides a passage-way for the central carrierrod 17, upon which is carried the guide-ring to which the requiredup-anddown movement is transmitted by'means of a cam or other suitablemeans. The bolstercase 10 is firmly secured to the spindle-rail 20 ofthe machine by means of a nut 21 upon its lower end, with a distancesleeve and washer 23 strung thereupon between said nut and the bottom ofthe spindle-rail to provide for carrying the delivery-spools uponradius-arms 24 24, pivoted upon said distance-sleeve, as described insaid pending application. The bolster-case 10 thus forms an annularoil-receptacle, in which the tubular spindle 12, with its collars 13 and15, is retained in vertical position while being rotated upon thestepbearing washer 14, with an annular wall of oil both inside andoutside of said tubular spindle, thus providing a verysatisfactorilysupported and thoroughly-lubricated spindlemounting.

What we claim is- A spindle mechanism comprising a tubular bolster-case10 having a central bolster 16 therein, a tubular spindle 12 inclosingsaid bolster without contacting therewith, and having top and bottomcollars centering the same in said bolster-case and an annular seat inthe latter, and a concentric pulley-sleeve forming a rigid portion ofsaid tubular spindle substantially as set forth.

In testimony whereof we afliX our signatures in the presence of twowitnesses.
